UNITED STATES PATENT. 1 13 ALEXANDRE SENEGAL AND EDDY GIBOUARD, OF ST. HYACINTHE, QUEBEC, CANADA.

GROOVING 'roon.

Application filed February 1 1925. Serial No. 9,322.

To all whomc' t may concern.

Be it known that We, ALEXANDRE SENEGAL and EDDY GIROUARD, subjects of theKin'g of Great Britain, residing at St; Hyacinthe, in the Province of Quebec, Canada, have vented certain new and useful Improve" mentsin Grooving Tools; and we do ,here-' by declare that'the. following. is a full,"clear,i and exact description of. the invention, such as will enable othersskilled in the art tov which it appertains to make and use'the same.

present stamped or drilled with perforations or grooves for providing a rough surface to act on the stock. If the perforations or grooves are stamped, they are soon filled by reasonof the leather resuming its original condition under pressure. It'is also found necessary at times to recut the grooves, even if they have been originally cut. p

The object of the present invention is to .provide a tool for' cutting the grooves originally if desired or-recutting thein'if neces sary after the machine has been in operation. The device consists of an arcuate; member adapted to engage the curved part of the roll or apron. The arcuate member or body carries a cutter and a pair of guide members so arranged as to tilt the-body and cutter.

Consequently, themoveinentf of the roll or apron against the cutter causes the formation of a spiral groove extending from one edge to the other. I

The invention is fully disclosed in the following description and in the accompanying drawings, in which Figure 1 is an elevation of the device;

Figure 2 is an elevation atright angles to Figure 1 showing the tool in operation; I

Figure 3 is a fragmentary longitudinal section thereof;

The present invention pertains to a novel Figure 4 is a section on the line 4-4: of Figure 3; V V

' Figure 12 is a front elevation thereof.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

"The tool comprises a back or body 1 of a-rcuate' formation and extending suhstan= tially through 180 degrees; To each side of the body is attached a guide meinben2 about half as long as the back and'havi'ng 8D the same curvature. Each guide hasa lip or edge adapted to protrude withinthe circle defined by the innered e of the body. The guides are heldto thehody by means of a common pivotpin t passed through therein.

i The lower end of the bodyis formed with a pair of spaced lugs 8 between which is pivoted a stem 9,the latter having a handle or knob 10 at its lower end. Above the members, a strap-11 is passed through the body and carries a central knob 12. A The upper part of the body is split longitudinally as at 13 and transversely at one side as at 14. The cavity thus formed is normally filled by a block 15 held in place by a number of screws 16. The meeting walls of the split top and blocks are formed with complementary inclined recesses 16. and still deeper inclined grooves 17. A V- shaped cutter 18 is inserted with its edges received in the grooves 17. The spaces 16 allow for the outlet, of material cut by the edge of the cutter.

uide A stud 19 is passed through the top of the body 1, into the recesses 16, and is journaled on a nub 2O projecting from the inner wall of the block 15. The outer end of the stud carries an operating knob 21, while the inner end is formed in the nature of a pinion 22. The latter meshes in grooves 23 cut transversely in the upper end of the cutter 18.

A spindle 2A is passed through the recesses 5 in the guide members and is journaled in the, body 1 as shown in Figure 4. The spindle carries opposite cams 25 received in the two recesses. One end of the spindle is provided with .an operating knob 26.

In the use of the device, one of the edges 8 will be projected and the other retracted with reference toth-e body 1 due to the relation of the cams 25. The knob 26 is set to give the desired extent of protrusion of the two edges. The tool is then applied to the apron or roll of a condenser or rubb machine. The form shown in Figure 11 is of the apron type consisting of two pairs of spaced rollers 27 one pair above the other, and an apron 28 trained over each pair. The tool is placed against the apron adjacent one end of one of the rollers so that the cutter is uppermost and the guides beneath as shown in Figure 2. The knobs 10 and 12 are held by the operator, and by means of them the tool is pressed tightly against the apron. The relation of the edges 3 as described above causes the tool to tilt slightly as a result of which the cutter is'also tilted. During movement of the apron from the rotation of the rollers 27 the cutter will therefore form a spiral groove 29 extending from one edge of the apron to the other. After the groove has been started, the protruding edge 3 will be received therein and the tool will thereby be guided transversely across the apron. The toolis then applied in the same manner to the remaining apron to form an oppositely inclined groove 30 as shown in Figure 12. The straight arrows to Figures 11 and 12 indicate the opposite oscillation of the aprons during rotation in a manner already ,known in the art.

While a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details of construction may be I our hands.

made without departing from the spirit of the invention as indicated by the appended claims.

Having thus fully described the invention, what we claim as new and desire to protect by Letters Patent is 1. A tool of the character described comprising a body, a cutter carried by said body, a pair of guide members attached to said body, and lips extending from said guide members unequally beyond one of the edges of said body.

2. A tool of the character described comprising a body, .a groove cutter carried by said body, a pair of arcuate guide members attached to said body, and lips extending from said guide members unequally beyond the inner circumference of said body.

3. A tool of the character described comprising a body, a cutter carried by said body, a pair of guide members attached to said body, and means for adjusting said guide members simultaneously in opposite directions. 1

4. A tool of the character described comprising a body, a cutter carried by said body,

a pair of arcuate guide members attached to said body, and means for adjusting said guide members simultaneously in opposite.

directions.

5. A tool of the character described comprising .a body, a cutter carried thereby, guide members pivoted to the sides of said body, lips extending from said guide members unequally beyond one of the edges of said body, said guide members being formed with recesses, a spindle through said recesses and through the body, and opposite cams mounted on said spindle and received in said recesses.

6. A tool of the character described comprising a body, a groove cutter carried; thereby, arcuate guide members pivoted to the sides of said body, lips extending from said guide members unequally beyond one of the edges of said body, said guide members being formed with recesses, a spindle through said recesses and through the body, and opposite cams mounted on said spindle and received in said recesses.

In witness whereof we have hereunto set ALEXANDRE SENEGAL. EDDY GIROUARD.
